Space rocks formed when the solar system was created billions of years ago are believed to have fallen to Earth near Grimsby in a fiery light show two weeks ago.
Astronomers will be digging through farmers' fields Thursday and Friday on the hunt for hunks of a meteor that blazed across the skies of southern Ontario Sept. 25 shortly after 9 p.m.
The beachball-sized meteor was first picked up by cameras operated by the University of Western Ontario's physics and astronomy department 100 kilometres above Guelph as the fireball streaked southeastward at a speed of about 75,000 km/h.
Astronomers at the university have traced the meteor's path and believe chunks of it may have landed above the escarpment within a 10-km radius of Grimsby.
"We're pretty certain something came down," said Phil McCausland, a postdoctoral fellow with the university's astronomy department.
